Does anyone know if you can set-up trunk to trunk tranfers on a succesion 4.5 machine that only has copper trunks? I know........... but it's a backwoods hospital . I tried everything I know last week, but still can't get back out of the switch to public network.The customer wants to be able to forward individual phones off-site, the calls come in through auto-attendant in call pilot. the forwarding off-site works if called internally.
